The Cheryl Deboer case really changed my view on who commits suicide. She was parking her car to join her carpool to work and decided to walk a few miles and end her life. No warning signs and no life changes and really so sad.
I think it is a possibility with Sherri, too. When there is information suggesting suicide, this is rarely released until after a body is found. I think its for a couple of reasons - they don't want to publicly shame the person if they have not committed suicide and the public will lose interest in assisting.
We have heard there were no mental health issues but we would hear that either way. If there is evidence of depression, it would explain the cancellation of the searches and the vague and incomplete picture (bordering on suspicious) of what had been going on. Also, LE said there had been no "major" calls to the house. This was probably discussed in detail and I missed it but what does that mean?
It could be an abduction, though. I don't think she has voluntarily walked away and I never thought the husband was involved. I fear it's going to end sadly.
